  • Objectives: The aim of this study is to analyze main problems on occupational safety and hygiene in construction sites and to suggest some improvement methods. In order to decrease industrial accidents, I emphasize the approach paradigm shifts according to characteristics of construction workers. Methods: Pointing out the irrationality of current institutions by comparing bad outcomes of occupational safety and hygiene in construction industry and characteristics of construction workers. Results: In order to decrease industrial accidents, we need some approach paradigm shifts; the supply method of industrial safety and health fundamentals on the construction industry level, the accident rate calculation by using the actual construction workforce instead of an estimation, institutionalizing the prevention efforts themselves for industrial accidents, securing enough production costs for the precondition of occupational safety and hygiene in construction sites. Conclusions: I ascertain the need of the approach paradigm shifts for decreasing industrial accidents in the construction industry.

  • An Economic Sentiment Indicator(ESI) is a composite indicator of business survey indices(BSI) and consumer survey indices(CSI). The ESI designed to reflect economic agents' (this includes producers and consumers) overall perceptions of economic activity in a one-dimensional index. The European Commission has published an ESI since 1985. This paper demonstrates the construction of an ESI for the Korean economy. The BSI and CSI components (having a high correlation and a leading feature with respect to GDP) are selected to construct the ESI and they are aggregated using a weighted average and then scaled to have a long-term average of 100 and a standard deviation of 10. Thus values greater than 100 indicate an above-average economic sentiment and vice versa. The newly constructed Korean ESI that extends to January 2003 shows a good tracking performance of GDP and adequately reflects the overall perception of economic activity.

  • 건설교통분야의 국가R&D사업 투자비중은 지속적으로 증가 추세이고, R&D 규모측면에서도 100억원 이상의 중대형 규모의 연구개발사업들이 많이 나타나고 있다. 그러나 국내에서는 지속적인 연구개발투자에도 불구하고 개발된 기술의 사업화가 추진되지 않는 기술 휴면화 현상이 대두되고 있고, 기술개발에 한정되어 있는 R&D사업 범위 확대를 통해 R&D성과를 사업화와 연계시킬 수 있는 방안 마련이 필요하다. 따라서 본 연구는 수익접근법을 이용한 기술가치 평가를 현재 진행 중인 연구사업에 대하여 기술가치 평가를 수행하여, 특허기술의 가치를 금액으로 산정하여 기술실시계약시 합리적이고 객관적인 기술거래 기준가격과 사업화 전략 등을 제시하였다. 해당 기술수명 기간 동안 창출 가능한 잉여현금흐름(FCF) 합계액(사업가치)은 할인율 16.34%를 반영하여 현재가치로 환산할 경우 512백만 원이 산출되었고, 해당 사업가치에 산업기술 요소법을 통해 구해진 기술기여도 44.39%를 적용한 결과 기술가치는 227백만 원으로 도출되었다. 이렇게 도출 기술가치 평가를 기반으로 기술의 사업화 및 상용화 전략수립이 필요하고, 이에 대한 사업화 요건과 마케팅 전략 등의 연구가 추후 추진될 필요가 있다.

  • The construction of the Great Korea Canal(GKC) In the Korean peninsular requires consideration from a aspect of vision of the national land development. GKC will bring enormous benefits to the Korean economy. First, effect of the equitable regional development. Second, reduction In freight transport costs and contribution of innovation in physical distribution. Finally, creation of large numbers of new jobs and development of Tourism & Leisure Industry and its related industry. Lets view the construction and finance supply.

  • The characteristics of construction work cause excessive strain on specific body parts of the construction craft workers. However, there are few tools to mane an accurate measurement of the load on the musculoskeletal system, and the musculoskeletal disorders (MSDs) experienced by the workers have not been properly understood. So, there is an urgent need for development of a tool to measure the load on the musculoskeletal system. Therefore, this research aims to develop a musculoskeletal load measuring device for construction workers. In order to eliminate the noise and errors, an accelerometer, gyro sensors and the Kalman Filter are used in the device developed in this research.

  • In recent years, construction projects have been forced to cope with lack of skilled labor and increasing hazard circumstance of human operations. A construction robotic system has been frequently accomplished as one alterative for overcoming these difficulties in increasing construction quality, enhancing productivity, and improving safety. However, while the complexity of such a system increases, there are few ways to carry out an assessment of the system. This paper introduces a knowledge-based multi-criteria decision-making process to assist decision makers in systematically evaluating an automated system for a given project and quantifying its system performance index. The model employs linguistic terms and fuzzy numbers in attempts to deal with the vagueness inherent in experts' or decision makers' subjective opinions, considering the contribution resulted from their knowledge on a decision problem. As an illustrative case, the system, called Robotic-based Construction Automation, for constructing steel erection of high-rise buildings was applied into this model. The results show the model's capacities and imply the application to other extended types of construction robotic systems.
